Manifestation of strong geomagnetic storms in the ionosphere above Europe
Original language description
This chapter addresses the ionospheric manifestation of geomagnetic storms induced by solar wind. Changes in the electron density distribution at the ionospheric F region heights above Europe during strong-to-severe geomagnetic storms, which occurred over present solar cycle, have been analysed. During storm main phase only negative phases dominate in summer, while during winter occurrence of both negative and positive phases is more probable. Enhancements of electron density have been sometimes observed several hours before the onset of geomagnetic storm. The effect on electron density at the F1 region heights at European higher middle latitudes has been found negative, if any at all. The stormy high latitude F region is most variable compared with middle and lower middle latitudes, being strongly influenced by magnetospheric processes, in particular, strong electric fields, which are usually present during geomagnetic storms.
